活性基 meaning in Chinese
active group
active radicals
Examples
- Emmobilzation studies of penicillin acylase on the porous bead with oxirane groups
以环氧乙烷为活性基的多孔颗粒状固定化青霉素酰化酶的制备 - Database of manufacturers producing acid , basic , direct , disperse , mordant , reactive , and solvent vat dyes and pigments for application in textiles , leather , plastics , and paper
-生产销售母体为偶氮型蒽醌型酞菁型等，活性基为x型k型kn型km型ke型r型p型等的活性染料 - The result shows that argon gas can not only promote the excitation of plasma at low pressure , but also improve discharge state , increase the density and activation of reaction radical and improve the quality of diamond films . on the other side , argon can cool the plasma and maintain low temperature of substrate due to its big ionization section and high collision probability with gas molecules
结果表明，气体系统中引入氩气一方面不仅有利于维持低压放电，而且改善放电状态，提高反应活性基浓度和活性，提高低温沉积金刚石膜的质量；另一方面，由于其大的电离截面使其和电子碰撞的几率大大提高，对等离子体进行冷却，有利于基片温度的降低。 - Thioredoxins , an ubiquitous small proteins with a redox active disulfide bridge in its conserved motif - cp ( g ) pc - , are universally distributed in eucaryote and procaryote and have a molecular mass of approximately 12kda . by its disulfide / dithiol interchange reaction , this protein can transmit the regulatory signals to seleted targets ( enzymes , transcription factors etc ) and plays an important role in many plant physiological processes that includes photosynthesis , dna synthesis , transcription , protein disulfide reduction , protein repair , filamentous phage assembly , cell apoptosis and seeds germinating and so on
该蛋白质中含有保守的- cp ( g ) pc -氨基酸活性基序，该基序中的两个半胱氨酸残基可通过巯基二硫键的转换实现其氧化还原状态的变化和电子氢的传递，对细胞中与氧化还原相关的多种生理过程的调节起重要作用。通过同许多酶类、蛋白类、细胞内活性因子相藕连， trx能对光合作用、 dna复制、基因转录、细胞凋亡和生长、噬菌体组装、蛋白质的还原和修复信号传导等生理过程产生影响和调节。
